rumors that is a programmed move to heat all small mining guys and just be for the future the big company's, also some medium farm's will be heated also, natural life..., could be a smart strategies or maybe not,now looks like the crash is coming 
That's not how mining works on Waves.
No coins are created by mining. Miners only lives by fees. You can't make pressure on smallest pools by manipulating the market.
From my own experience, be a small miner or leasing on a big pool is almost rewarding you by the same. The biggest factor for miners is peoples using the platform to generate fees, then grab them.
You can check here: http://dev.pywaves.org/generators/ and see that even small miners have a good ratio. That's even more true since the network voted for the FairPoS.
